I want to use my GSX Magneto against my buddy this week. I am looking to make the most of his Trait:

MAGNETIC FIELD:

Magneto can use Energy Shield/Deflection. When Magneto uses the Carry ability, he can carry up to 4 characters. Modify Magneto's combat values by +1 if he's occupying a square that contains a debris marker.

I'd also like to get up on some elevated terrain to be able to rain down the fury. So I was looking at some maps that had elevated terrain, and walls. The 'problem' is that most of them have walls that border both elevated and grounded terrain, like so:

EEEEEEEE
WWWWW
GGGGGGG

So, if I was to break one of the Wall sections, does it create a debris marker at both elevations?

I see no reason it would not.

I thought the same, but I thought that I'd read something (did a search and turned up nothing) to the contrary before.
